 Overview:
  Drupal is prone to a cross-site scripting vulnerability and an
  information-disclosure vulnerability.

  An attacker may leverage these issues to obtain potentially
  sensitive information, execute arbitrary script code in the browser
  of an unsuspecting user in the context of the affected site, steal
  cookie-based authentication credentials, or control how the site is
  rendered to the user; other attacks are also possible.

  These issues affect the following:

  Drupal 5.x (prior to 5.17)
  Drupal 6.x (prior to 6.11)
